Disposed in each Fig.4 is a fragmentary top plan View of the of the housings 25 and 26 is astud 36, the rear end portion of which has abutting engagement with thelug 22 as best shown in Fig. 3. The studs 36 include constrictedportions 37 on each of which is mounted one end of a coil spring 38. Theopposite end of each of the coil springs 38 is secured to a stop 39 bymeans of soldering or the like and these stops 39 are movable throughthe passage 32 for a the clear lenses 19. In the event that the springs38 become worn and partially lose their elasticity, the screws 40 may bescrewed inwardly and secured in position by means of the nuts 41, thusretracting the springs 38 and increasing the force exerted by thesprings on the studs 36 and consequently increasing the friction betweenthe studs 36 and the lugs 22.

The frames 27 and 28 have slots 42 formed therein and in these slots Iprovide dark lenses 43 and 44 which may be of any color and type as willbest serve the purpose.

It will be seen, therefore, that when desiring not to use the darkcolored lenses 43 and 44, the wearer of my improvedgoggles may move themupwardly out of the line of vision by grasping the ear 31 and thepressure exerted by the springs 38 on the studs 36 and in turn thefriction of the studs 36 against the lugs 22 will support the frames 27and 28 and enclosed dark lenses 43 and 44 in any convenient angle out ofthe line of vision. It will likewise be .seen that' when the dark lenses43 and 44 are moved upwardly out of the lineof vision the wearer may usethe clear lenses 19 for any purpose requiring. protection of the eyesagainst flying chips or splinters of metal and the like withoutnecessitating a change of goggles or the wearing of two differentgoggles.

From the foregoing description of my invention it is manifest that Ihave provided an improved construction in goggles which whileeffectively serving its several objects will be highly eflicient in useand economical in manufacture.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification, without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the modificationsas come within the scope of the appended claims.

Having thus described my invention what I clainras new and desire toprotect by Letters Patent is:

of said frames and including portions pivotally connected to each ofsaid bosses, a stud in each of said tubular members, and a spring ineach of said tubular members having one end bearing against said studwhereby to force said studs into frictional engagement with said bossesto retain said frames in a predetermined position with respect to saidtransparent lenses.

2. In goggles, eye pieces adapted to house transparent lenses andinterconnected by a head band, a boss projecting from each eye piece atthe front thereof, a pair of frames each housing a colored lens, meansfor interas I connecting said frames to said bosses, said meanscomprising a. tubular member on each of said frames andincluding'portions pivotally connected to each of said bosses, a stud ineach of said tubular members, a spring in each of said tubular membershaving one end bearing against said stud whereby to force said studsinto frictional engagement with said bosses to retain said frames in apredetermined position with respect to said transparent lenses, andmeans for adjusting the tension of said springs including a memberthreaded into the end of each of said tubular members opposite saidbosses.

In testimony whereof I affix my signature.
